Holding force boosts


shrink film ExxonMobil recently showcased its Exceed XP material at Chinaplas, to make three-layer soft shrink packaging film. The material’s controlled


holding force and toughness allows the fabrication of a film that provides high integrity wrap, overwrap and bundle packaging for delicate or irregularly shaped products. It was demonstrated on the booth of Huashan Plastics Machinery.


‘Soft-shrink’ films can


protect and preserve delicate products, such as pizza and cheese products, or bathroom and kitchen tissues. Converters benefit from


improved bubble stability which can optimise machine performance and increase output. As a single bubble solution with balanced shrink, it offers operational stability and a cost-effective alternative to double bubble polyolefin films. Separate to this, the


company demonstrated how a combination of its Exceed and Enable materials could be combined using blown film technology to produce differentiated liquid and food lamination packaging solutions. It demonstrated the three-layer liquid lamination at Chinaplas, at an open house held by Jinming Machinery (Guangdong). ❙ www.exxonmobilchemical.com

Wrapping film portfolio extended with 18 new colours


Avery Dennison Graphics Solutions has expanded its Supreme Wrapping film portfolio, with 18 new colours.


The additions include eight colours in a satin


metallic finish, new single colours in gloss metallic, diamond and matt, and a new gloss finish option for the existing ColorFlow series. A new green-to-purple colour shifting


material, Lightning Ridge, has also been added in both satin and gloss finishes. “These new materials combine an arresting


POLYCARBONATE Bus shelters turn on the style


visual impact with ease of installation,” said Oliver Guenther, marketing director at Avery Dennison Graphics Solutions Europe. “The films offer easy positioning, long term remov- ability and bubble-free application.” The Supreme Wrapping Film portfolio now


offers more than 100 colours and finishes. Easy Apply RS air egress technology allows the films to be repositioned and applied bubble-free while the adhesive is long-term clean removable. ❙ www.averydennison.com


Covestro has supplied its Makrolon UV polycarbonate sheet for a bus shelter in Pitts- burgh, USA – showing how form and function can be combined. The shelter is equipped


with overhead canopies from Exterior Technologies (Extech) Covestro’s polycarbonate sheet glazing material. Extech needed a strong,


lightweight, light transmitting glazing material for Skyshade 3300, a surface-mounted, single-glazed translucent industrial canopy system that covers 5,000 sq ft. “Covestro helped us choose


the right glazing material based on the project require- ments provided by the transit authority,” according to Jim Leslie, general manager of Extech.


Other key benefits of the sheet include: a higher impact resistance than glazing products like glass and acrylic; advanced UV resistance technology to give good outdoor weathering perfor- mance; and, ease of installa- tion and fabrication. The tough nature of


Covestro’s product has been seen in another application, in which its Makrolon 15 sheet


formed the basis of a secure glazing school for a school that had previously been vandalised.


“School security has


traditionally been a key application,” said Tom Niziolek, architectural segment manager for polycarbonate sheet at Covestro. “In the case of Sister Thea


Bowman Catholic School, there was a direct need to use durable Makrolon 15 to help eliminate the future threat and cost of vandalism,” he added. ❙ www.covestro.com
